Universal Gravitation Objectives * Compare and contrast gravitational force vectors as mass and distance are changed. (Explorations 1‚ 2‚ and 3) * Discover how changes in the distance between two objects affects the gravitational force between them. (Explorations 1‚ 2‚ and 3) * Describe how changes in the masses of two objects affects the gravitational force between them. (Explorations 1‚ 2‚ and 3) Description of Activity In this activity‚ you will explore how distance and mass

Circular Motion and Gravitation Circular motion is everywhere‚ from atoms to galaxies‚ from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general‚ we say that an object rotates when the axis of rotation lies within the body‚ and that it revolves when the axis is outside it. Thus‚ the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis‚ all the particles of the body revolve – that is‚ they move in circular paths about

Newton ’s Law of Universal Gravitation Gravity if one of the four fundamental forces in the universe. Though the fundamental principles of it eluded scientists until Sir Isaac Newton was able to mathematically describe it in 1687 (Eddington 93). Gravity plays a serious part in everyday actions as it keeps everything on the ground; without gravity everything would be immobile unless a force was applied (then it would move infinitely because there would be no force to stop it). Perhaps‚ the

Assignments in Science Class IX (Term I) 10a Gravitation IMPORTANTIMPORTANT NOTES NOTES IMPORTANT NOTES 7. Acceleration due to gravity of the Earth : The acceleration with which the bodies fall towards the earth is called acceleration due to gravity. Its average value is 9.81 ms–2. 8. Variation of acceleration due to gravity. (i) Acceleration due to gravity changes with the change in distance from the centre of the earth. (ii) Acceleration due to gravity is maximum at the poles of the earth

There is a popular story that Newton was sitting under an apple tree‚ an apple fell on his head‚ and he suddenly thought of the Universal Law of Gravitation. As in all such legends‚ this is almost certainly not true in its details‚ but the story contains elements of what actually happened. What Really Happened with the Apple? Probably the more correct version of the story is that Newton‚ upon observing an apple fall from a tree‚ began to think along the following lines: The apple is accelerated

Newton’s Laws of Cooling & Universal Gravitation Law’s of Cooling: Newton’s law of cooling is used measure the temperature change of an object of some temperature placed in a place of a different temperature. The law states that dT/dt= k(T-R) where T is the temperature of the object at time t‚ R is the temperature of the surrounding of the place (constant) and k is a constant of proportionality. This law states that the rate of change of temperature is proportional to the difference between

7.1 Newton’s Law of Universal Gravitation Newton’s Law of Universal Gravitation states that: Every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Consider two particles of masses m1 and m2 separated by a distance r. Each will exert a force F on the other‚ given by where F : gravitational force between the two particles. m1‚ m2 : masses of the
